－You could call them if you wanted to know where they were.

A．have been away from	B．had been away from
C．had left	D．had gone

Answer 1

B

試題分析：句意：---當我到家的時候，我的父母已離開家?guī)讉�小時了。我沒遇到他們。---假如你想知道他們在哪里的話，你可以給他們打電話。當我到家的時候是過去時間狀語，所以我的父母已離開家?guī)讉�小時了。for a few hours表示一段時間，不能與非延續(xù)動詞連用。所以要用過去完成時態(tài)。故選B.
